# eModul vs iQua

The clearest difference is rating: iQua at 4.7 against eModul's 1.5. iQua also leads on ratings volume (957 vs 2) and update cadence (every 6 weeks vs every 3 months). eModul's advantage is monetization model (free vs ad-supported) and device support (3 vs 1).

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
